In London, Horse Barns Reborn as Trophy Homes

Once upon a time, London ran on horsepower. And behind the city's great townhouses were mews—rows of urban stables to accommodate carriage horses and their grooms.

Over the past 100 or so years these humble quarters have had to adapt to survive—being used initially as garages for early motorcars and later as quaint pied-à-terres. Now, amid the boom in prime areas of London, developers are transforming mews into luxury homes.
